Description
Technical field
The invention belongs to field of mould production, and in particular to a kind of virtually to match somebody with somebody mould method based on measurement.
Background technology
Mould is a kind of precision instrument for making formed article, and different moulds is made up of different parts, is had higher
Processing request.The production process of mould includes：Mold design, numerical control programming, roughing, heat treatment, finishing, with mould, throw
Light and die trial process., it is necessary to repaired a die with mould with examining die quality according to mould result after the completion of mould finishing
Work.
For the Virtual assemble of mould, traditional method is by means of computer aided, to assembling for product
Property evaluation carry out intuitively description and expression, and provide three-dimensional animation to show the assembly simulation process of product, effectively checking dress
Correctness and reasonability with technique, product design personnel are made to find and exclude in time design defect and hidden danger.
Existing craft by the way of cavity plate, punch-pin apply red lead, after punch-pin is contacted with cavity plate, passes through sight with mould method
Examine its red lead and tint situation to examine mold parting surface crudy, carry out repairing a die by hand accordingly, this process is repeated, finally
Complete die joint and match somebody with somebody mould.The method is high to Personnel Dependence, can not quantify overproof amount, and once the success rate with mould is low, with imitating
Rate is low.
The conventional e measurement technology of manufacturing includes three coordinate measuring engine measurement, optical measurement and on-machine measurement etc., can be with
The CD data of product is drawn according to the measurement point of selection.At present, still mould is matched somebody with somebody without using e measurement technology progress mould
Method.
The content of the invention
It is an object of the invention to for above-mentioned the problems of the prior art, there is provided a kind of virtually to match somebody with somebody mould side based on measurement
Method, this method can provide the guide data that repairs a die, and mould success rate and efficiency with mold are once matched somebody with somebody in raising, reduce to personnel according to
Rely.
To achieve these goals, the technical solution adopted by the present invention comprises the following steps：
1) read in and the measurement data of analysis model file and reference plane, obtain world coordinate system under assembly environment and
Punch and matrix initial local coordinate system, reference plane measurement data is grouped, and is fitted reference for assembling plane；
2) the reference for assembling plane of fitting is grouped, successively entered reference for assembling plane in locked mode precision in group
The fitting constraint of row face, solves and updates punch-pin local coordinate system, each group result is fitted to obtain punch and matrix local coordinate system；
3) punch and matrix die joint measurement data is read in, according under the punch and matrix local coordinate system and assembly environment of solution
World coordinate system, punch and matrix die joint measurement data and detection direction are subjected to Coordinate Conversion, make the measurement on punch and matrix
Point is all switched under the world coordinate system of assembly environment, and the detection direction collection on cavity plate is transformed into the world of assembly environment
Under coordinate system, die joint interference analysis is carried out in die joint accuracy rating, calculating difference, draws the overproof point of die joint；
4) according to the overproof point of die joint, tree control and graphic software platform are carried out, output virtually matches somebody with somebody mould result.
Punch-pin, cavity plate reference measurement point set are respectively divided into four groups according to mould reference plane first in described step 1)
Datum mark subset, each datum mark subset is then fitted to two reference for assembling planes respectively.
In the packet of each reference for assembling plane, four reference planes of mould are divided into two groups according to diagonal, each
The corresponding two reference for assembling planes of the reference plane of mould, are grouped according to the reference plane of mould and are grouped reference for assembling plane.
Described step 2) cavity plate initial local coordinate system fixed first, calculates two assemblings and carries out face with datum plane respectively
Punch-pin local coordinate system after fitting constraint, and two punch-pin local coordinate systems are fitted, solve final punch and matrix
Local coordinate system.Described step 2) is first carried out the punch and matrix reference for assembling plane of the first composition pair in locked mode precision
Face fitting constraint, solves and updates punch-pin local coordinate system, and in each calculate, keeps existing restriction relation to be asked
Solution, fail if there is solving, then exit and virtually match somebody with somebody mold process；Second group of punch-pin local coordinate system is carried out using same method to ask
Solution.
Described step 3) is in mathematic interpolation, and node-by-node algorithm punch-pin measurement point, cavity plate measurement point are on detection direction
Difference, and record difference.Described step 3) enters each point difference when the overproof point of die joint judges with die joint precision successively
Row compares, and is non-super not good enough when absolute difference is not more than die joint precision；When absolute difference is more than die joint precision, it is
Overproof point；If difference is just, judgement measurement point has gap；If difference is negative, judge that measurement point has interference.
Step 4) is virtually with mould result by drawing and report display, in tree control and graphic software platform, in control and figure
Overproof point is shown in shape window with non-super not good enough, and is distinguished in different colors, overproof value is shown in tree control；Virtually match somebody with somebody mould knot
In fruit drawing and form, drawing shows overproof point and numbering, the numbering of report display die joint whole measurement point, difference amount and super
Poor situation.
Compared with prior art, the present invention has following beneficial effect：E measurement technology and Virtual Assembling Technology are integrated
Apply to mould and match somebody with somebody mold process, Virtual assemble is carried out using measurement data and model file.The present invention virtually matching somebody with somebody based on measurement
Mould method is calculated according to mould measurement data file and mold former file after finishing automatically by computer,
Including being fitted reference for assembling plane, mould locked mode analysis is carried out, and then calculate the overproof point of die joint.The invention enables mould to match somebody with somebody mould
Method of the process without using applying red lead by hand in the past, then reduce mould with the manual steps in mold process, quantified to match somebody with somebody
It the overproof amount of mould key point, can instruct to repair a die, improve and once match somebody with somebody mould success rate, improve efficiency with mold.
